FYI that heat-sink is clamped onto a peltier cooler, which is sinking the 5v line from the PC PSU. This is actually blowing chilled air into the box, you can actually feel the cold.
After losing a RAMPS stepper driver to heat it seemed like a plan!

That fan's about 6 bucks from eBay but seems to have some reasonable puff. If anyone has another cheap off-the-shelf suggestion I'll post up the STL for that too. The fan is open both sides, and the recent photo shows a TEC and heatsink topside, which now blows chilled air into the box and gives real kick-ass cooling whilst sucking up some amperage from 5v line of the ATX PSU.
